Tokyo plans underground missile shelter near major railway hub

Tokyo authorities have greenlit construction of an underground missile shelter in the vicinity of Tokyo Station, one of Asia's most heavily trafficked railway facilities. The project represents a significant civil defence initiative as Japan grapples with the escalating security environment in Northeast Asia.

The shelter construction comes in response to repeated ballistic missile test-launches conducted by North Korea in recent months. The tests have heightened regional tensions and prompted neighbouring countries to reassess their civilian protection infrastructure.

Japan has progressively strengthened its defence posture over the past year, upgrading early warning systems and reviewing evacuation protocols. The Tokyo Station shelter project underscores the country's commitment to safeguarding critical infrastructure and civilian populations in major urban centres.

The facility will be designed to accommodate large numbers of people during ballistic missile incidents and other emergency scenarios. Officials have not disclosed specific timelines or estimated costs for the project, though the shelter is expected to be integrated with existing Tokyo Station infrastructure to minimise disruption to commuter operations.

The initiative reflects broader regional concerns about North Korea's advancing weapons capabilities and its willingness to conduct provocative military displays.
